1 Claim.

This invention relates to shower pipe cleaners for pulp, paper, board,and shingle machines and has for an object to provide a novel cleanerplug in the shower pipe and valve controlled pipes for reversing theilow of water'through the shower p-ipe to alternately move the cleanerplug from one end of the shower pipe to the other to thereby effectivelyclean the jet openings in the shower pipe in minimum time and withoutmanual exertion.

A further object is to provide a device of this character which will beformed of a few strong simple and durable parts, which will be inexf'pensive to manufacture and which will not easily get out of order.

With the above and other objects in view the invention consists ofcertain novel details of cony struction and combinations of partshereinafter yfully described and claimed, it being understood thatVarious modifications may be resorted to within the scope of theappended claim without departing from the spirit or sacricing any of theadvantages of the invention.

In the accompanying drawing forming part of this specification,

Figure 1 is a longitudinal sectional view of a wire covered cylinderused in machines of the class described and showing a shower pipe andcleaner plug therein constructed in accordance with the invention.

Figure 2 is a detail sectional view drawn to enlarged scale, and showingthe plug at the opposite end of the shower pipe from the position shownin Figure 1.

Figure 3 is a detail perspective view of the cleaner plug.

Figure 4 is a side elevation of a shower pipe and valve controlledsupply pipe and showing a modied form of cleaner plug.

Figure 5 is a side elevation, with parts in section, showing two valves,opening oppositely, in lieu of the three-way valve illustrated inFigures 1 and 4.

Referring now to the drawing in which like characters of referencedesignate similar parts in the various views, IU designates a cylinderof the type used in pulp mills and the like, the same being covered withwire screen I I, and being equipped with hollowed journals I2 which aremounted in pedestals I3 or other suitable supports.

In carrying out the invention a shower pipe I4 is mounted in thecylinder vto extend longitudinally thereof close to the screen Il and isprovided with elbows I3 at the ends into which short pipes I4 are fittedand these latter are also equipped with elbows I5 which receive pipes I6that extend through the hollow journals I2.

In order that water may be let into the shower .pipe from either end andsprayed against the wire screen through the jet openings Il in theshower pipe, a supply pipe I8 is provided with a conventional three-wayvalve I9 to the housing of which are connected branch pipes which extendoppositely to each other and are equipped with elbows 2|. Short pipes 22are connected together by a coupling 23, and these pipes are connectedto the elbows 2I and to elbows 24 that are secured to the ends of thebeforementioned pipes I6 which extend through the hollow journals I2.

Mounted to slide longitudinally in the spray pipe is a cleaner plug forpreventing clogging of the jet openings I'I. in Figure 3 to comprise apair of discs 25 and 26 having passages 2l formed therein. These discsare xed on a short rod 28. A pair of disc valves 29 and 30 are slidablyfitted on the rod and are of suicient size to close the passages 21 inthe discs 25 and 26. Stop collars 3| and 32 are xed to the rod and limitopening movement of the disc valve 30.

In practice when the three-way valve I9 is turned in one direction waterwill ilow as indicated by dotted lines in Figure 1 whereupon the valve29 will be forced open and moved against a stop collar so that continuedflow of the Water will push the cleaner plug endwise to the opposite endof the shower pipe during which time the cleaner discs 25 and 26 willwipe over the jet opening I'I and remove clogging material. By reversingthe three-way valve the flow will be as indicated by arrowheads inFigure 2 so that the cleaner plug will be moved in a retrogradedirection to the opposite end of the shower pipe.

A modified form of the invention is shown in Figure 4 in which theshower pipe 33 is provided with supply pipes 3G and 35 at the endsthrough which the water may be fed in either direction to the showerpipe. In this embodiment of the invention a supply pipe 36 is equippedwith a three-way valve 3l. The pipe 34 enters one end of the housing ofthe valve. A pipe 38 enters the other end of the housing and isconnected to a pipe 39 which in turn is connected to the pipe 35.

By turning the three-way valve in one direction the flow in the showerpipe will be through the pipes 39, 38 and 35 as indicated by thearrowheads and when the valve is reversed the flow will be reversed andwill enter the shower pipe through the pipe 34.

The cleaner plug is best` shown The cleaner plug 40 illustrated inFigui- 4 may be simply a wood plug having an axial opening to receive arod 4I. The plug is centered on the rod by means of stop nuts 42 whichare threaded on the rod outside of the ends of the plug. The operationof the plug is the same as previously described, the plug when moved ineither direction by flow of Water serving to Wipe over and open the jetopenings 43 of the shower pipe.

In Figure 5 there is shown a modified form of valve which may be used inlieu of the three-Way valve. In this modied form of Valve a pair of plugvalves 44 and 45 are mounted so that their 1 openings 45 and il willturn respectively opposite to each other so that when one valve is openthe other valve is closed and thus flow from the; supply pipe 48 throughthe branch pipes 49 and 50 to the shower pipe, may be reversed.

For simultaneously manipulating the valves 44 and 45 the handles 5I and52 of the valves are extended parallel to each other and are connectedby a link 53 so that both valves will move in unison.

From the above description it is thought that the construction andoperation of the invention will be fully understood Without furtherexplanation.

What is claimed is:

A cleaner member adapted to be reciprocated longitudinally in a vpipe bythe reversal of liquid oW, comprising, a rod, spaced discs on the rod ofsubstantially the same diameter as the bore of the pipe to be cleaned,said discs having passages therethrough, Valves slidably mounted on therod-between said discs for controlling said passages, and stopv collarson lthe rod intermediate said valves and against which said valves abutWhen actuated away from said discs to establish said passages in opencondition.
